I don't envy you. This is a particularly nasty experience is not dealt with in the proper manner. You need to advise your household Insurers immediately. There is not just the loss of oil but also the damage that it can cause to property adjacent to the spill. It can goes as far as effecting your foundations if not treated properly and can even be an environmental hazard if the quantity is large enough. You may need to temporarily move accomodation. Who caused the spill, was it just an accident by yourself or was it during delivery.
